This paper describes the development of an USV (Unmanned Surface Vehicle) prototype that serves as an educational
platform and can be use for coastal patrol and operations in the jungle. The USV length is less than 2 m and range of
5000 m. It's composed by the following modules: propulsion, power, motor driver, CPU, sensor suite, camera system,
communication and weapon system. The weapon system is formed by an experimental assault rifle and a rocket launcher
with a fire control system. The assault rifle haven't got mechanical moving parts, the bullets (7.62x51mm round) are
electronically ignited. The CPU is an FPGA development kit. The USV can be operate in remote mode or fully
autonomous. Results of some systems from laboratory and sea trials are show.
The present work describes the development of two collaborative Autonomous Underwater Vehicles (AUV) for
Antarctic exploration to use them in the Ecuadorian Expeditions to the Scientific Base Pedro Vicente Maldonado in
Antarctica. One vehicle is an AUV, called TAUV, with classical torpedo architecture, can work as a platform to transport
scientific payload in a determined path in open waters. The TAUV length is 2m and diameter of 0.16m and has got three
degree of freedom: pitch, yaw and surge. The vehicle achieves stable control with a set of three pairs of control planes.
The other vehicle is an AUV, called HAUV, with Hybrid architecture that combines the best characteristics of the ROV
and AUV, high stability in the water column, high maneuverability at low velocity without control planes and efficient
hydrodynamics. The HAUV length is less than 1.50 m. The propulsion module is formed by four thrusters, three axial
and one oriented vertically, this configuration gives to the HAUV three degrees of freedom: heave, surge and yaw. This
vehicle can works as a ROV or an AUV. The hybrid configuration features the vehicle to explore dangerous areas near to
the glacier wall. Three collaborative behaviors are discussed: formation flying, point inspection near to the glacier wall,
replacement of a missing vehicle. Results of some systems of the TAUV and HAUV from laboratory, sea trials in
tropical waters and Antarctic environment are show.
